Detailed Description

Delphi FP10469 is a fuel injection pressure regulator engineered for vehicles that require consistent fuel pressure at the rail. Delphi draws on OE experience and supplier knowledge developed over decades of original-equipment service, and that background is reflected in the fit, materials, and pressure specification of this replacement part. This unit uses a metal housing, a push-in inlet, a hose-style outlet, and bolt mounting for straightforward integration into the fuel delivery system.

Compatible With 1992-1998 Hyundai Sonata, N/A; 1992-1995 Hyundai Elantra, N/A; 1990-1994 Hyundai Excel, N/A; 1991-1992 Hyundai Scoupe, N/A; 1990-1994 Mitsubishi Eclipse, N/A; 1989-1993 Mitsubishi Galant, N/A; 1989-1992 Mitsubishi Mirage, N/A; 1990-1994 Mitsubishi Precis, N/A; 1988-1992 Dodge Colt, N/A; and 1990-1994 Plymouth Laser, N/A. This part cross-references Dorman OE Solutions 800-293 and Standard Ignition PR181 for the same application.

What It Helps Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle related to pressure regulation issues
• Fuel trim problems tied to inconsistent rail pressure
• Driveability concerns in aging fuel injection systems

Installation Notes and Tips

Verify inlet and outlet sizing before installation: the inlet measures 16.0 mm (0.63 in.) and the outlet measures 9.0 mm (0.35 in.). Confirm the vehicle uses a bolt-mounted regulator with a push-in inlet and hose outlet layout, and match the 51 system pressure specification to the original application. Inspect fuel lines, seals, and surrounding components for wear before reassembly.

Quality Assurance

Delphi builds this regulator using OE heritage and technical knowledge developed through service to major automakers. That background supports accurate fitment and consistent fuel system control for select Hyundai, Mitsubishi, Dodge, and Plymouth models.
